摘要
山区河流港口陆域岩质边坡内部结构复杂,在水的渗流作用下,边坡极易遭到破坏。利用有限元强度折减法对山区河流港口陆域岩质边坡在渗流作用下的稳定性进行了分析。结果表明:不同的水位变动幅度对岩质边坡的稳定性影响差异明显,并得出在水位大幅度下降的过程中,回水变动区内外岩质边坡的运动状况截然不同。这可为今后边坡监控提供理论指导。
Rock slope of river port land in mountainous area is of complex internal structure,and the slope is very easily to be destructed with the water seepage.The strength reduction finite element is used to analyze the stability of rock slope of port land with water seepage in mountainous area.The results show that： different change ranges of water level can differently affect the stability of rock slope;in the process of a significant drop of water level,the movement trends of the rocky slope inside and outside backwater area will be completely different.These results can provide theoretical guidance for slope monitoring.
